Problem with Connectors in Qlik Sense February 2020
In the Load Data page the connections take very long to load. Until yesterday they would eventually do it. Today I started seeing an "Unknown connection type" in the Rest connections that prevented me to continue.
https://support.qlik.com/articles/000039813 provided two workarounds. One removing connectors from the C:\Program Files\Common Files\Qlik\Custom Data. Then, yes, the connections load very quickly, but I need to use a Rest connector so this does not work for me. Workaround #2 referred to an article applicable only to Qlik Sense 3.x.
When I leave the QvRestConnector in the Custom Data, in Google Chrome Dev Tools I see an error "Failed to load connector: undefined".
I've installed the latest version of Qlik REST Connector (2.21.0). It didn't help.
